'SPECIFICATION forming part of Letters Patent No. 267,334, dated November 14, 1882.

Application tiled July 21, 1882.

To all whom tt may concern Be it known that I, Z. DAVIS, of Canton, in the county of Stark and State of Ohio, have invented certain new aild useful Improvements in Vapor-Stoves; and I do hereby declare the following to be a full, clear, and exact descrip-v tion of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawing, which forms part of this specication.

The present invention has relation to certain new and useful improvements in that class of vapor-stoves provided with a safety-reservoir, in which is employed means for drawing the gasoline or oil from the burners previous to filling said reservoir, and thus prevent serious accidents, which frequently occur when the reservoir or other vessel is being filled While the burners are lighted.

Previous to my invention, in this class ot' vapor-stoves the reservoir was provided with a movable plunger ot' somewhat less diameter than the interior diameter ofthe reservoir, so that the plunger would work loosely therein and allow the oil or gasolineto pass in its course between the interior sides of the reservoir and exterior ofthe plunger. Although this plunger, in its action, draws the oil or gasoline from the burners, when raised to the top of the reservoir it in no way could act in the same capacity as a tightly-fitting piston, as the gravityot' the oil or gasoline alone is depended on to draw it away from the burners when the plunger is raised.

1t is the object of my invention to provide means whereby a greater certainty of action is obtained, and more perfect in its results in extinguishing the burners, and instead of a loosely-fitting plunger, operating as above specified, I employ a tightly-fitting piston located at any suitable point between the reservoir and the burners, and adapted to draw the oil or gasoline away from the burners by creating a vacuum, and thus instantly extinguish the llame.

It further consistsin the combination of the oil-reservoir and cover therefor, with a piston and piston-rod, the piston being connected to the cover, so that the removal of the cover for the purpose of filling the reservoir will cause (No model.)

the flames to be instantly extinguished, as will be more fully described hereinafter.

The object of my invention is to provide a safety attachment to vapor-burners, so as to extinguish the flames from every burner whenever the cover is removed from the reservoir for the purpose of filling it.

The accompanying drawing represents a vertical section of myinvention.

A represents an oil-reservoir of any suitable shape or construction, and into which the oil is poured forthe purpose of feeding the burners in the usual manner. Upon the top 0f this reservoir is formed a funnel or mouth, C, of any suitable form, so that the reservoir can be readily iilled from a can or vessel of any kind. The cover B, which covers this mouth, is intended to close it sufficiently to prevent any evaporation of the uid, and yet to allow suiicient air to tlow through into the reservoir to insurea steady supply of oil to the burners...

This cover B is here shown as being made simply cup-shaped, so as to fit down over the mouth; but Ido not limit myself to this par ticular construction, for any other that may be preferred may be used.

To the under side of the reservoir is attached in any suitable manner the cylinder N,in which the piston P moves. Connected to this pistou is the piston-rod O, which extends up through and is fastened to the cover B, so that whenever the cover is removed for the purpose ot' filling the reservoir the piston will be drawnupward in the cylinder N, so as to cause a vacuum in the lower portion of the cylinder, and through this vacuum a suction upon each of the burners of the stove. The upper end of this cylinder is contracted, as shown at K, so thatthe piston cannot beacciden tally pulled up too far, and thus allow a sudden rush of oil from the reservoir through the pipes. Through the lower end of the cylinder, just above the lowest point at which the piston rests, is made a suitable opening, O, through which the oil tlows from the reservoir to the burners.

Outside of the lower end of the cylinder is made a suitable enlargement, Q, through which the oil flows around the lower end of the cylinder down into the supply-pipe.

I do not limit myself to the precise location IOO ofthe piston and cylinder, for they wllpoperate equally as well when placed below the level of the burners as when placed above them. It' so desired, aT coiled or other suitable spring may be secured to the bottom of the piston, so as to draw it back into position as soon as the piston-rod is released. One great source of danger with vaporburners is that people, not knowing;r the (langer,willattempttollthereservoirwhile the burners are lighted. Explosions and accidents are almost sure to happen, and hence the object ot' my invention is to extinguish the lames in the very act of raising the cover, and thus make accidents impossible.

Having thus described my invention, I claim- 1. The combination, with a vapor-burner, oilreservoir, and supply-pipe thereof, ofa tightlyfltting piston adapted to operate substantially as and for the purpose speci tied.

2. The combination, with a vaporburner and an oil-reservoir, of asupply-pipe, the piston, the piston-rod, and the cover for the reservoir, whereby the removal of the cover of the reservoir will cause the burner or burners to be extinguished, substantially as specified.

In testimony whereof` I ax my signature in presence of'two witnesses.

ZEBULON DAVIS.
